Water is a key factor in desert restoration. The goal is to capture
all the rain that falls, reduce plant water loss and stress with
protective shelters and to provide uniform, very efficient
irrigation only when necessary. Deep pipe, porous hose, buried clay
pot, wicks and other innovative systems can reduce water lost to
evaporation. This makes it possible to grow plants even in the most
challenging desert conditions at reasonable cost, even if water has
to be hand carried. As plants start to grow they continue to improve
the environment by increasing water and nutrient capture. This in
turn increases growth in a positive feedback loop that can lead to
site recovery much more quickly than expected in the desert.
